The total change in water level Over the two years is 3½ inches
Using the parameters given for our Calculation;
- Change in year 1 = - 2⅓ inches
- Change in year 2 = -1⅙ inches
The total change in water level can be calculated as ;
- Change in year 1 + Change in year 2
Now we have
- 2⅓ + (-1⅙)
- 2⅓ - 1⅙
= - 3½
Hence, the total change in water level Over the two years is 3½ inches .
